Safety Glasses for Protection with gray frame color and gray lens color. Ideal for morning and afternoon use, as they provide excellent visibility even in shady conditions. The lenses maintain clarity and are bright enough to reduce reflection, even in foggy or misty conditions. They have tinted lenses that have the same shade at all light levels. Adding color to your glasses can help if you are particularly sensitive to light. Due to the polycarbonate lenses, their use is recommended for safety glasses and athletes' glasses. These lenses are 10 times more durable than regular organic lenses or crystals. Their durability does not mean they do not break, but they can provide additional safety if users engage in activities that can cause their glasses to break. The anti-reflective lenses they have drastically reduce reflections on the lenses and allow a higher percentage of visible light to reach the eyes. Thanks to their sun protection, the lenses filter 100% of both UVA and UVB rays.
